Application filed October 2, 1897. `Serial No. 653,878. (No model.)

To all whom it may concern:

Be it known that I, GEORGE Ross-LUND, a citizen of the United States, residing at Bergen, Norway, have'invented certain nevsT and useful Improvements in vKnockdovvn Barrels and the Like, of which the followingis a specification.

This invention relates to certain improvements in knockdown barrels and the like; and the object of the same is to so place and hold the staves together by means of bands or straps as to facilitate the assembling of the parts of barrels, casks, and the like, the tightening of the staves, and the knocking down of the barrel to facilitate the return shipment.

A further object of the invention is to so put the staves together and connect them that any internal or external pressure acting on the individual staves is distributed over the adjacent ones and the displacement of the staves relative to one another is avoided. i

My invention consists of certain details of construction which will be fully described hereinafter and linally pointed out in the claim. V

In the accompanying drawings, Figure 1 represents a side elevation of my improved knockdown barrel shown partly in section. Fig. 2 is an end elevation showing the construction of the head. Fig. 3 is an outside view of the staves, showing the same in knockdoWn position. Fig. 4 is an enlarged detail transverse section showing clearly the construction of the staves. Fig. 4 is a det-ail of the fastening device for thel strap or band. Fig. 5 is a detail view of some staves, showing a modified construction in which ventilating-orifices for the barrel are provided. Fig. 6 is a longitudinal section of a tube constructed in accordance With the invention.

Each stave A is formed in one of its longitudinal edges with a fluting or semicircular concave chamfer d and along its other longisponding in contour exactly, or nearly so, with the contour of the said chamfer, always in accordance with the radius desired. The part of the edge of each stave near the outer face thereof is left square or straight along its whole length to form a shoulder adapted to prevent the staves being pressed inward from the outside or outward from the inside.

Three or more transverse grooves h are made in the staves, said grooves being adapted to receive metallic bands or straps d. The

grooves are formed in the outside surface of `each stave at suitable distances apart and the d allow a subsequent tightening of the bands Without interference by the nails or other fastenings.

The outer surface of the staves may be either fiat or curved, according to the purpose for Which the article tobe built up is to be employed. lf the staves are to be used for casks, they are formed on their inner faces, near the ends, 'With crozes or grooves a for the heads of the casks.

The bands or straps Clare tightly applied to the exterior of the staves when the barrel or cask is built up by means of a locking device, which to some extent resembles the Well-known c0tton-bale tie, but with this difference, that one endonly of the band or strap is turned to the inside, While the other end is turned to the outside, both ends being passed through the steel buckle or tie F,which is held in position by the inwardly-bent end of the strap,while the other end can be pulled forcibly through the buckle by means of a suitable tool, so as to tighten the strap around the staves.- As soon as the straps are drawn tight, so that the staves of the barrel rmly hug the heads, the outwardly-bent end of each strap is folded on the stave and retained thereon by means of a sliding sleeve f, that is placed on the strap and moved over the out- Wardly-bent end of the same.

The cask is built up as follows: The separate staves are held around the cask-heads and so placed together that the tongue b of one stave engages in the chamfer ct of the adjacent stave. The bands or straps are then connected by means of the fastening devices F f.` The tie or fastening device secures the rigid connection of the stave, While it permits at the same time the readyknocking down of the barrel, (Whenever this should be required when returning the same to the place of shipment,) which is accomplished by loosening IOO the bands orstraps after removing the sleeves f from the outwardly turned ends of the straps, so that these ends can be passed through the buckle or loops and the staves unrolledand spread out flat.

The Cask-heads are preferably constructed as shown clearly in Fig. 2. The head consists of three parts-namely, g g g2*the outer parts g' g2 being segments of a circle, while the central part g is of wedge shape in length. The central Wedge-shaped part g is preferably thicker than the outer parts and has its longitudinal edges beveled, so that when the bands are tightened it is effectively wedged between the outer parts of the head, so as to produce a thoroughly-tight joint.

. For some purposes, however, I prefer to construct the head of the barrel in one piece. In case a barrel cannot be entirely iilled a third head may be arranged in the same to cover the contents and to prevent their shaking about. It also serves to strengthen the barrel. Such a third head is shown by way of example at h, Fig. I. This inner head may be utilized as a special or separate cover for the contents of an open cask or barrel. Vhen the barrel or cask contains goods which require ventilation, the staves are constructed, as shown in Fig. 5, with longitudinal apertures i, formed by recessing the meeting edges of the staves. lVhen the casks are intended for holding powder or other substances necessitatin g the very tight joints, the chamfering s and tongues of the staves may be coated with any suitable luting or cement, and for certain purposes-for instance, petroleumoil-'the casks may be lined with tin-plate or other impenetrable lining. On the same principle tubes may be constructed as shown in Fig. '6. These tubes may be made of any required length, the ends of the staves being perfectlyjoined together by means of an outer sleeve K, which is composed of short staves connected by the straps and bands the same as in the barrel and cask, so that when the staves of the" tube proper are pressed together the staves of said sleeve can also be pressed together for securing a joint between the sections of tube. It is evident that these tube-'sections may also be made to slide telescopically one on the other. Barrels constructed on this principle are preferably of cylindrical shape, as shown 5 but they may be made also of oval or other shape. Aft-er use the barrels may be knocked down, so that they will take up comparatively small space on return shipment.

Having thus described myinvention, what I claim is The combination, with a series of staves, of which each stave is provided with exterior transverse recesses and with a croze at each end, rivets, nails or the like projecting outwardly from the staves, and heads set into the crozes of the staves, of bands or straps placed into the-recesses of the staves and provided with -narrow slots into which said rivets or nails project, and fastening devices or ties consisting of a buck-le attached to one end of each strap and a loop for each strap, one end of each strap being passed through said buckle and being returned and passed through the loop on the strap, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my n-ame in presence of two subscribing witnesses.
